Students at Manhattan’s selective Stuyvesant High School will have to retake their Regents exams after a widespread cheating scandal emerged last month, Schools Chancellor Dennis Walcott announced Monday.

School officials discovered the cheating when they found junior Nayeem Ahsan photographing his Spanish Regents exam. After they confiscated his phone, administrators found texts and information about the Spanish, English and physics Regents tests.

The Department of Education is not only invalidating exam results for Ahsan and the other 69 students who cheated, but they are reportedly suspending him beginning in September, Walcott said.

In a separate incident, another Stuyvesant student cheated on a physics Regents exam by passing notes, a DOE spokeswoman told DNAinfo. That student will be suspended and have to retake the exam.

“It’s not acceptable,” Walcott said on John Gambling's WOR show Monday morning. “We’re not going to tolerate it.”

Cheating has long been a problem at the Battery Park high school, where high-achieving students struggle to keep up with academic pressure.

“Cheating has taken place for who knows how long,” said Walcott. “Now with technology—and that’s why we banned cell phones—people have the ability to use new technology to try to cheat.”

The next phase of the Stuyvesant cheating investigation will examine whether the administration and teachers handled the cheating scandal appropriately, Walcott said.
